FE²�?ZNS CRYSTAL FUNDAMENTALS EXPLAINED

KLuS 2 one crystal samples undoped and doped by using a very low (five %) or superior (38 %) concentration of trivalent thulium or ytterbium ions were synthesized in the form of slender hexagonal plates. The very low phonon Electrical power (�?20 cm ⁻�?) was confirmed employing Raman spectroscopy. Samples have been analyzed also through the u
